Sorry buddy, seems like a waste on money to me. I never seen any difference being made buy indexing you broad head to match your vanes. If you talking about nock indexing in regard to arrow spine well that diffident ball game..... Also with a system like this you loose the functionality of being about to add addition weight to the back of your insert which would add much more befit and ease of tuning comparably speaking.
Haven't seen that before, but I just bought & installed these: http://www.clean-shot.com/locknloads.htm While I agree that indexing blades to match your vanes doesn't have much value, I will be indexing my blades to match each other. I figure if a BH acts as a steering wheel, enhancing any tuning flaws, I'd like them to all steer in the same direction. I honestly got them more for their gluelessness, than their indexing capability.
A easy and cheap way to accomplish what your doing without buying different expensive inserts... Just use two part epoxy, attach your regular insert to your broadhead insert the insert turn it to line it up where you want it...let dry and your set. If you ever reflectch the arrow just index your knock before you put it into your jig.
It hasn't made any difference for me but I use Quick Fletch so before i dip them i always line my cock vane up with one of the blades on my broadheads only because I use the mathews t5 quiver and it has pre-molded places for the blades on your broadheads and i have a touch of OCD where I have to have all of my cock feathers pointing out i just think it looks good but thats only me as far as shooting it makes no changes I can see.
I use hot melt glue for my inserts so to rotate them i just use hot water and a BH wrench or a lighter with pliers with a field tip attached, but I really havent noticed a difference in the flight. I keep my heads and vanes uniform so they are quieter in my quiver in case of a miss if i need a second shot.
Looks like a solution to a problem that I didn't know I even had I've always used O-rings, they're cheap and easy. No special tools required, low probability of failure.
